|"blue screen error code 0x0000007B"|
STOP: 0x0000007B (parameter1, parameter2, parameter3, parameter4)
There are MANY different things that can cause that error.
A boot Sector virus is one of the LEAST likely things that would have caused your error.
Boot Sector viruses are NOT common theses days - I have NOT encountered one for many years - if you were using any anti-malware software at all that has a resident module - a part that runs in the background all the time looking for suspicious activity - then it's extremely unlikely you have a boot sector virus, because the anti-malware software would have probably found it before it could do any damage .
The 0x0000007B error is generated by Windows, NOT the bios.
The fact that you were getting that error indicates your computer itself booted fine, the bios was working fine, the bios found the hard drive has a bootable partition, but when the Windows operating system attempted to load from the hard drive it encountered something that caused the 0x0000007B error.
There is lots of info on the web about troubleshooting the 0x0000007B error.

Two things that I have found that often get rid of this error
- See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
(Too late for you do this now since you zero filled the drive)
- run CHKDSK /R C: in the Recovery Console
For more info,
see response 11 in this:
starting at, scroll down to "If that won't work....."
"I Have a Acer Aspire intel Dual core (motherboard Type N1996-002185CEOC6E)"
That may all be useless info.
N1996 merely indicates the mboard meets the N1996 standard - that has nothing to do with the mboards's model number.
-002185CEOC6E may also be useless.
"with partitioned Magic I zero-ed the complete HD to be sure the virus was gone. "
If you zero filled the entire hard drive, then there CANNOT be any malware on the hard drive .
"By trying to reinstall windows XP, a question was asked boot on virus <Yes/No> so logically I say NO .."
Clear as mud. That's useless info, unless you can quote the exact message you got.
You don't normally get any such message while installing XP from an XP CD.
"But the Virus was still on there."
If you still got the STOP 0x0000007B while trying to install XP from the CD on a hard drive that has been zero filled, then that error CANNOT be caused by any data on the hard drive because it doesn't have any significant data on it yet - that has to be caused by a hardware problem.
"So I cleared the BIOS with the jumper next to the battery.
And now my BIOS is gone, PC doesn't boot anymore ???"
Did you move the Clear Cmos jumper back to it's "normal" position after you did that ? If you didn't the computer may not boot.
Assuming you moved the Clear Cmos jumper back to it's "normal" position after you did that, clearing the Cmos DOES NOT cause the mboard itself to not boot.
You WILL get a "CMOS CHECKSUM ERROR" or similar message after you have cleared the Cmos, because all Cmos settings in the bios have been set to defaults including the current Date and Time - you must go into the bios and set at least the current Date and Time, Save bios settings, then you won't get that message again while booting
You get the same message when you remove the mboard battery then install it again
NOTE that is NOT the same thing as booting - loading - the operating system from the hard drive. Your hard drive will NOT be found to be bootable by the bios until you have installed XP on it again.
"The strange thing is that some times the hard drive or CDrom spins up, the HD is recognized in the BIOS, and sometimes it just doesn't even starts the BIOS cycle ??"
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
Your no boot at all problem can also be caused by a failing power supply if it's a desktop computer.
Failing power supplies are common and can cause your symptoms.
Check your PS.
They often partially work, fans and hard drives may spin, leds may come on, yet you may get no video and the mboard will not boot all the way.
See response 4 in this:
If you can borrow a power supply from another working computer, try connecting that.
If it is failing, you can usually replace it with any decent quality standard sized standard ATX PS with the same capacity or greater.
Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.
